Abstract

Light pollution, particularly artificial light at night (ALAN), is an increasingly pervasive environmental issue with profound effects on nocturnal insect activity and broader ecosystem health. As urbanization and technological advancements illuminate the night sky, the natural rhythms and behaviors of countless insect species are disrupted. This paper provides a comprehensive review of how light pollution alters nocturnal insect behavior, physiology, population dynamics, and ecological interactions. It synthesizes current research, highlights knowledge gaps, and discusses conservation strategies, emphasizing the urgent need for tailored lighting solutions and policy interventions to mitigate the adverse impacts on insect biodiversity and ecosystem stability.
